Specification of Letters Patent.

Patented March 30, 1909.

Application filed June 14, 1907. Serial No. 379,033.

To all whom it may concern:

Be it known that I, BERNICE J. NOYES, of Boston, county of Sufiolk, State of Massachusetts, have invented an Improvement in Ironing and Drying Devices for Paper-Making Machines, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

machines and has for its object to construct an improved form of drying ap aratus for the web, which is adapted to dr t 1e web after it has been formed and partia 1 dried by other means, and to so construct t e drying apparatus that the web may be drawn over or moved with respect to its web-engaging surface, whereb the surface'of the web is ironed or artially iished at the same time that the web is dried.

In carrying'out this invention the drying and ironing device is movable in the direction of movement of the web, and has a curved surface over which the web is drawn.

It may be made as a cylinder, and means provided for revolving it at a speed at variance to the velocity of the moving web, as for instance, the surface speed of the cylinder may be less than the velocity of the web or it may be more, depending upon which way it is desired to lay the fibers, but in either event the direction of movement of the drying and ironing device is in the direction of movement of the web. At least two drying and ironing devices will be employed, which are arranged to engage the opposite sides of the aper and to deflect it. The drying and ironing devices are adjustable with respect to the pa or, to vary the extent of deflection, so that t e drying and ironing action may be varied.

The web fromthe drying c linders of a Fourdrinier machine may be de 'vered to the d g and ironing apparatus forming the siilij eict matter of this application and subse uently to the calender or to a winder.

igure 1 shows in plan view a portion of a paper-making machine, having a drying and ironing apparatus embodying this invention. Fig. 2 is a side elevation of the apparatus shown in Fig. 1. Fig. 3 is a transverse section of the apparatus shown in Figs. 1 and 2 taken on the dotted line 33. Fig. 4 is a modification showing in diagram a set of drying and ironing rolls arranged between This invention relates to paper makingthe drying cylinders of a paper-making mamchine.

Referring to the drawing, a, d, represent two cylinders of suitable dimensions which are adapted to be heated. These cylinders are made substantially alike and are operated by similar means, so that one only need be described in detail. The cylinder a is provided with hollow journals a, for the inlet and outlet of steam, and said journals are supported in bearing boxes (I. of any suitable construction. The bearing boxes are vertically adjustable, as for instance, they may be mounted on screws a arranged in suitable upright supports. The web passes over the cylinder a, and said cylinder is disposed to deflect the web, and the extent of deflection may be regulated by adjustment of the cylinder toward and from the web by means of the screws a By varying the position of the cylinder with respect to the web and thereby varying the extent of deflection, the web Wlll be acted uplon with a varying degree of pressure so that t e ironing action and also the drying action is varied.

The cylinder a is revolved by any suitable means so far as this invention is concerned, and, as herein shown, one of the 'ournals a has fixed to it a bevel-gear b, w ich is engaged by a bevel-gear b, splined upon and adjustably secured to an upright shaft b having at its lower end a bevel-gear I), which is engaged by a bevel-gear-b, secured to one of the journals of a air of friction conepulleys c, of any usua or suitable construction. B means of the cone-pulleys, which are revo ved by any suitable means, not shown, the cylinder a will be revolved and its speed regulated. It is designed and intended to revolve the cylinder in the direction of 9" the moving web but at a speed at variance to the velocity of the movin web, as for instance, the surface speed of t e cylinder may be less or more than the velocity of the moving web. The web will be fed forward by a pair of positively driven feed-rolls, and by said rolls will be drawn over the cylinder, and as the cylinder is revolved at such time in the direction of the moving web,- it will be observed that the web is moved over the moving cylinder. As the cylinder is heated and as its surface is made smooth and polished, the web will be dried and also ironed to a certain extent, as it is drawn over it; The cylinder d is arranged at the opposite side of the web and is operated in the same manner as the cylinder a and by similar means, so that both sides of the web will be acted upon.

It Wlll be observed that the cylinders herein shown are isolated,thatis to say, they are separated from each other and from the other operating parts and do not have cooperating with them another roll, to thereby feed the web.

Referring to Fig. 4, the cylinders a and d are arranged between the usual drying cylinders of the paper-making machine, and they will be revolved and adjusted substantially the same as the cylinders shown in Figs. 1 to 3.

Having thus described my invention, what I claim as new and desire to secure by LettersPatent is 1. In a paper making machine, the combination with means for moving a web, of an isolated roll arranged to deflect the Web having a web-engagin surface, and means for revolving said rol in the direction of movement of the web and at a speed at variance to the velocity of the moving web, substantially as described.

2. In a paper making machine, the combination with means for moving a web, of an isolated roll arranged to deflect the web having a web-engaging surface, means for heating the roll, and means. for revolving said roll in the direction of movement of the Web and. at a speed at variance to the velocity of the moving web, substantially as described.

3. In a paper making machine, the combination with means for moving a web, of an isolated roll, arranged to deflect the web, having a web-engaging surface, and means for adjusting it to vary the extent of deflection of the web, and means for revolving said roll in the direction of movement of the web and at a speed at variance to the velocit of the moving web, substantiall as descri ed.

4. In a paper making machine, the com bination with means for moving the web, of two isolated rolls, arranged at opposite sides of the web, to deflect it in opposite ways, having web-engaging surfaces, and means for revolving said rolls in the direction of movement of the web and at speeds at variance to the velocity of the moving web, substantially as described.

5. In a paper making machine, the co1nbination with means for moving the web, of two isolated rolls, arranged at opposite sides of the web, to deflect it in opposite ways, having web-engaging surfaces, means for heatin said rolls, and means for revolving said ro Is in the direction of movement of the web and at speeds at variance to the velocity of the moving web, substantially as described.

6. In a paper making machine, the con1- bination with means for moving the web, of two isolated rolls, arranged at opposite sides of the web, to deflect it in opposite ways, having Web-engaging surfaces, means for adjusting them to vary the extent of deflection of the web, and means for revolving said rolls in the direction of movement of the web and at speeds at variance to the velocity of the moving web, substantially as described.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.

BERNICE J. NOYES.
